Did you ever wonder how the CIA got all of those hostages out of Tehran? Well, wonder no more. According to Variety, George Clooney and Grant Heslov, the men behind Good Night, And Good Luck., are developing a script tentatively titled Escape From Tehran. It will chronicle the CIA's plan to use a fake movie production as a means to free a handful of captive Americans during the 1979 hostage crisis.

The film will be based on an article Joshua Berman wrote for Wired magazine. Premiering in this month's issue, the piece describes how CIA operative and master of disguise Tony Mendez saved six US citizens stuck in Tehran.

With the help of two make-up artists, the CIA was able to create the fake Studio Six Productions and announced its new film that was to begin shooting in that country. Even the trade papers were duped into posting bogus stories about the project.

When Mendez found the hostages, he had them pretend to be Canadian location scouts for a soon-to-be released Hollywood blockbuster. The plan worked.

There is no set date on when the actual film will go into production.

George Clooney is currently directing and starring in the 1920s sports pic Leatherheads which opens on December 7th, 2007. Grant Heslov also worked on the project.
